我正在尝试在Excel中编码，我需要锁定1-7行和A-C列

Question

我对 Excel 编码还很陌生，所以我有点困扰。但是，我想尝试锁定特定列，这些列只能由相应的用户解锁。它有效，但是当我尝试使其始终解锁特定行和列时，它会解锁所有单元格。我不知道为什么......我对其进行了编码，以便首先锁定所有单元格，这是我遇到问题的代码：

ws.Cells.Locked = True
Debug.Print "All cells locked"
    
' Prompt for global password to unlock Rows 1-7 and Columns A-C
globalPassword = InputBox("Please enter the global password:", "Global Password Required")
If globalPassword = "GO123" Then ' Replace with the actual global password
    ' Unlock Rows 1-7 and Columns A-C
    ws.Rows("1:7").Locked = False ' Unlock Rows 1 to 7
    ws.Range("A1:C50").Locked = False ' Unlock Columns A-C in the specified range
    MsgBox "Rows 1-7 and Columns A-C are now unlocked.", vbInformation
    Debug.Print "Rows 1-7 and Columns A-C unlocked"
Else
    MsgBox "Incorrect global password. Access denied.", vbExclamation
    Exit Sub ' Stop further execution if global password is wrong
End If

我尝试使其与用户输入各自列的密码后解锁某些列的方式相同。而且，虽然它不起作用，但因为我认为 A1:C50 是问题所在，因为它会不断给出以下错误：

错误：无法设置 Range 类的 Locked 属性

所以我只是将其更改为 A1:A50 来先测试一下，并认为它有效，但我想不会，因为它实际上会解锁所有单元......

这应该可以解决你的问题

Sub LockAndUnlockCells()
    Dim ws As Worksheet
    Dim globalPassword As String
    
    ' Set the worksheet you are working on
    Set ws = ThisWorkbook.Sheets("Sheet1") ' Change Sheet1 to your sheet name
    
    ' Lock all cells
    ws.Cells.Locked = True
    Debug.Print "All cells locked"
    
    ' Prompt for global password to unlock Rows 1-7 and Columns A-C
    globalPassword = InputBox("Please enter the global password:", "Global Password Required")
    If globalPassword = "GO123" Then ' Replace with the actual global password
        ' Unlock Rows 1-7 and Columns A-C
        ws.Rows("1:7").Locked = False ' Unlock Rows 1 to 7
        ws.Range("A1:C50").Locked = False ' Unlock Columns A-C in the specified range
        MsgBox "Rows 1-7 and Columns A-C are now unlocked.", vbInformation
        Debug.Print "Rows 1-7 and Columns A-C unlocked"
    Else
        MsgBox "Incorrect global password. Access denied.", vbExclamation
        Exit Sub ' Stop further execution if global password is wrong
    End If
    
    ' Protect the worksheet to enforce lock settings
    ws.Protect Password:="yourSheetPassword" ' Replace with the desired sheet password
    Debug.Print "Worksheet protected"
End Sub
